What is the drop phenomenon of diesel generator?

Because the diesel engine with the use of multiple pressure seal forms, such as cylinder piston piston ring??, turbocharger? Supercharger rotor shaft, this seal usually has about 1/3 load in diesel engine, to give full play to the role, if empty load or load is small, there will be slight leakage phenomenon that is, we often say that the drop of oil. So what is the phenomenon of drop oil caused? Below for everyone to do a detailed answer.
If the unit is running under a small load, the following fault may occur after a long period of operation:
1 piston cylinder seal? Well, oil channeling, into the combustion chamber, the exhaust take the blue smoke.
2 for turbocharged diesel engine, due to low load or low air load pressure. It is easy to cause the sealing effect of the turbocharger oil seal (non-contact) to drop. The oil is forced into the plenum chamber and the air enters the cylinder.
3 on the part of the engine cylinder to participate in combustion, part of the oil can not be fully combustion, in the valve, inlet, piston top, piston rings and other parts of the formation of carbon deposits, as well as part of the exhaust emissions. In this way, the cylinder sleeve will be gradually accumulated in the exhaust pipe oil, will form carbon deposits.
4 supercharger chamber oil accumulation to a certain extent, it will naturally leak from the combination of the turbocharger leakage.
5 long term small load operation, may lead to increased wear of moving parts, engine combustion environment deterioration and other serious consequences lead to overhaul period.

Here we also remind you that Diesel generator sets should be used to minimize the low load or no-load operation time, the minimum load should not be less than 25% of the rated power of the unit, so as to ensure the effective operation of the unit.
